Onychomys [O. leucogaster和O. torridus]（0-16 kHz）由2种基本的新生儿发声类型和4种基本的成人发声类型组成。其中两种发声类型，1个新生儿和1个成人，显示20-64 kHz音频频谱内的主要超声元素。一个不寻常的响亮和纯音成人呼叫（9.5-13.5千赫）的地理，非地理和个体差异进行了检查。在单变量和多变量分析中使用6个特征的呼叫，区分种，性别和个体之间是可能的。没有证据表明大规模的地理模式的呼叫特征。近亲个体似乎有相似但可区分的叫声，并且有一些证据表明身体大小和叫声频率之间存在反比关系（较大的动物声音较深）。呼叫可以作为维持远距离个体间接触的一种手段，因此包含大量对其他蚱蜢鼠潜在有用的信息，包括：呼叫者的方向、距离、呼叫者的物种、呼叫者的性别、年龄（无论是成年还是幼年）和呼叫者的体型。这种发声具有很高的潜力，用于远程普查的自然Onychomys种群，并将作为一个自然的标记，监测个别蚱蜢小鼠在未来的实地研究。
The sonic portion of the vocal repertoire of Onychomys [O. leucogaster and O. torridus] (0-16 kHz) consists of 2 basic neonatal and 4 basic adult vocalization types. Two of these vocalization types, 1 neonatal and 1 adult, show major ultrasonic elements within the 20-64 kHz audio spectrum. An unusually loud and pure-tone adult call (9.5-13.5 kHz) is examined for geographic, non-geographic and individual variation. Using 6 characters of the call in both univariate and multivariate analyses, discrimination was possible between species, sexes and individuals. There was no evidence for large-scale geographic patterning in call characteristics. Closely related individuals appear to have similar, though distinguishable calls, and there is some evidence suggesting an inverse relationship between body size and call frequency (larger animals have deeper voices). The call may function as a means of maintaining interindividual contact over long distances and, as such, contains a large amount of information of potential use to other grasshopper mice including: direction of the caller, distance, species of the caller, caller''s sex, age (whether adult or juvenile), and caller''s size. This vocalization has a high potential for use in remote censusing of natural Onychomys populations, and will function as a natural marker for the monitoring of individual grasshopper mice in future field studies.
